The thermal insulation is one of the important materials in the construction that prevents heat transfer from the environment to another. Adjustment of ambient temperature is one of the effective factors in providing the necessary conditions for comfort in the building. The use of thermal insulation saves energy, as it can exchange heat to the surrounding environment. This is also important for protecting the environment. In some cases, insulation may affect the cost of construction for construction. It is important to know that this cost of building thermal insulation will later be offset by energy savings, and another place to worry about heavy payments. There is no. It goes without saying that thermal insulators are also resistant to fire in addition to their thermal insulation. This is because the ingredients of this type of insulation are condensed. One of the most common types of thermal insulation is wool that was used in the past, but today, with the advancement of technology, other types of thermal insulators have been produced that are better capable and minimize energy consumption.
What is the thermal insulation?
Heat moves from warm to cold place. As a result, heat insulation is used to prevent heat enter the cold environment. As a result of insulation, the interior of the building is kept warm in the summer, cool and winter. In order to have the right choice in buying thermal insulation, you first need to consider the ambient temperature and weather conditions of the location. Also, the thickness of the thermal insulation should be as much as possible to prevent energy loss. A good thermal insulation must have high compressive and thermal resistance, moisture resistance, and lack of fungus or mildew growth. Heat insulation is usually found in walls and ceilings, especially the outer walls of the house where heat is obtained or lost. If you live in an area where the weather is different in different seasons, your insulation should be accompanied by the principles of proper design. If your place of residence is always warm or cold, your insulation is included in the design.
Types of thermal insulation
There are various types of thermal insulation that are used for the walls, ceilings, floors and other areas needed in the building. The types of thermal insulation are:
Stone wool insulation
rock wool is a very high thermal resistance. The source of stone wool is from the basalt stone from volcanic activity. The thermal resistance of the stone wool is as much as insulation in refineries, power plants for pipe insulation and massive tanks. The ingredients of rock wool are capable of tolerating the temperature of about 750 ° C. That is why rock wool is known as a condenser insulation. In addition to thermal insulation, rock wool is also sound insulation and can be used for insulation, especially in crowded places. Another feature of this type of insulation is water absorption and moisture, which makes it not possible to grow fungi or mold in rock wool insulation.
Wool insulation
One of the most well -known thermal insulators is rock wool. This type of thermal insulation is obtained by the melting glass, which eventually becomes glass fibers during processes. Glass wool is considered to be a thermal insulation in which its fibers are capable of imprisoning the air, thereby preventing it from moving out. Wool is used both as thermal insulation and acoustic. It is low weight and this is an important advantage for places where lightweight is very important. The flaw that has glass wool, in addition to causing skin allergies, is that it is not resistant to moisture, but in cases where glass wool is needed in humid places, coated glass wool is used to more resistant to aluminum. Equal to moisture and moisture.
Elastomeric insulation
Elastomeric insulation, also known as blanket insulation, is one of the most popular types of thermal insulation. Since this type of elastomeric insulation is made up of non -toxic substances, it is known as environmentally friendly insulation. Because it has no harm to humans and the environment. Elastomeric insulators are commonly used in air pipes and canals. Other features of elastomeric insulation:
Easy installation
Corrosion resistant
Resistant to contamination such as dust
Ultraviolet
The high price of elastomeric insulation compared to other insulators such as stone wool and glass wool is one of the disadvantages of this insulation. It is also not very resistant to noise pollution, so it does not perform well and it is best to use effective sound insulation.
Izuham insulation
Isoham's insulation is a type of multipurpose insulation that has a variety of capabilities, including building reinforcement and optimal use of fuel. This type of insulation is made of hollow polyester with nanotechnology. Isoham insulation provides simultaneous heat, sound and moisture transfer. One of the features to consider when choosing insulation is its lightness. Isoham insulation has this feature, so it is a great option for applications such as building. Other benefits of Isoham insulation include: conductor and non -flammable, lack of skin sensitivity, insect -resistant, no need for infrastructure installation, sunlight resistant, etc.
Polystyrene insulation
Polystyrene insulation is a high -powered thermal insulation. This type of insulation is produced in both expanded and extruded forms and is available in the market. Polystyrene insulation can be used to apply the walls, floors and roofs of the building. The surface of this insulation is highly uniform, can be easily cut and installed in the desired spaces. Polystyrene insulation can also be used for outside the building. This type of polystyrene is stable, so it can be used in a variety of molding. Other benefits of polystyrene insulation include:
Growth -resistant
Water absorption and moisture
Easy transportation
Incorrect
Non -toxic
Recyclable
Perlite insulation
Perlite insulation is another type of thermal insulation that is used in various industries due to poor conductivity, low hardness, non -combustion. Perlite is a flammable material and can maintain its insulation properties at high temperatures. This type of insulation is resistant to termite attack and decay; But one of the disadvantages of perlite insulation is its low compressive strength. This type of insulation, like sponge, has holes that absorb water, which reduces the insulation resistance to moisture. Also causes respiratory problems.
Polyurethane foam insulation
Polyurethane foams are a great insulation. Today, polyurethane foam uses non -chlorocarbon (CFC) gases as a blower. This helps reduce the harmful effects of the ozone layer. They are relatively lightweight and weigh about two pounds per cubic feet. They have R-Value about R-6.3 per inch. Another advantage of this type of fire is fire resistance.
Cellulose insulation
Cellulose insulation is one of the most compatible types of environmental insulation. Cellulose is produced from recycled paper, cardboard and other similar materials and appears loose. Some current studies on cellulose suggest that it may be a great product to minimize the damage caused by fire. Due to the compression of the material, cellulose can have almost no oxygen inside it. Without oxygen inside the material, the damage is minimized. Cellulose is one of the most resistant to fire insulation. However, it has important disadvantages, such as the sensitivities that some people may have on paper dust. However, cellulose is a low -cost and effective method for insulation.
